4 protons and 4 neutrons
As atomic number increases from 1 to 82, the ratio of neutrons to protons in stable nuclei generally increases. For lighter elements, stable nuclei tend to have a neutron-to-proton ratio close to 1:1. However, as the atomic number increases, more neutrons are needed to offset the repulsive forces between the increasingly numerous protons, resulting in a ratio that can exceed 1.5:1 for heavier elements. This trend helps maintain nuclear stability amidst the growing electrostatic repulsion among protons.
Isotopes are atoms of the same element that have the same number of protons, but different numbers of neutrons, and therefore different masses. Unstable isotopes are radioactive and undergo radioactive decay of their nuclei, while stable isotopes do not undergo radioactive decay.
it isn't - the number of electrons in an atom will be the same as the proton number of that atom, but the mass of an atom includes the number of neutrons, and in every stable element heavier than hydrogen, the number of neutrons is the same as or greater than the number of protons. Also, the mass will vary between isotopes of the same element, which will contain the same number of protons and hence electrons but a different number of neutrons. Generally, in stable nuclei, as the number of electrons in an atom in creases, the mass increases as well, but these are not directly linked as to be stable, heavier nuclei require a greater proportion of neutrons in the nuclei so will have a greater mass to electron number ratio
A stable atom with 90 neutrons could potentially have a maximum of 90 protons, as the number of protons would have to be equal to or less than the number of neutrons for the atom to be stable.
Heavy nuclei are most stable when their neutron-to-proton ratio approaches 1. Nuclei with too many or too few neutrons compared to protons will have higher instability. This balance contributes to stability by preventing the repulsion between protons from overpowering the attractive nuclear force.
Stable nuclei have a balanced number of protons and neutrons, while unstable nuclei have an imbalance, leading to radioactive decay.
Stable nuclei have a balanced number of protons and neutrons, while unstable nuclei have an imbalance. Unstable nuclei undergo radioactive decay to become more stable.

The band of stability graph shows that there is an optimal ratio of protons to neutrons in atomic nuclei for stability. Nuclei with too few or too many neutrons compared to protons are less stable and tend to undergo radioactive decay.
The band of stability in chemistry refers to the range of stable isotopes on a graph of the number of neutrons versus the number of protons in atomic nuclei. Isotopes within this band are more stable because they have a balanced ratio of neutrons to protons. Nuclei outside of this band may undergo radioactive decay to become more stable.

The ratio of neutrons to protons in stable nuclei generally increases as the atomic number increases from 1 to 82. This is because as the nucleus becomes larger and more complex, it needs more neutrons to provide the necessary binding energy to hold the protons together due to the repulsive force between protons. This helps to maintain nuclear stability.
